    Great lecture series; I've studied many of these things in the past but this is so illuminating.

    Amazing video, in those 20 minutes I learned more than in my undergraduate semester course.
    But don't we need f to be continuous in Morera's theorem?

      Yes, I should have said f is continuous.

      Integration is dual to differentiation.
      Divergence (entropy) is dual to convergence (syntropy).
      The word entropy means "a tendency to diverge" or differentiate into new states -- reductionism.
      The word syntropy means "a tendency to converge" or integrate into a whole -- holism.

    At 17:00, wouldn't the condition be |z| > R instead of |z| < R?

    For the first application...anyone knows why f is hol. on C but not necessarily inside C? 4:56

      It's just an assumption i.e. "let's assume f is on hol on C, what can we then say about f inside C using this theorem we just proved?"

    I didn't get it on the proof cauchy's integral formula RUclips.lecturer kindly repeat the concept in a different manner
